Sažetak
The development of models for the quick bimass estimation of dominant Mediterranean tree and shrub species is an important part of long-term research on competition between forestry and livestock grazing in Croatia. This paper introduces regression models for estimating biomass above the ground in the second growth forest that were developed for Pubescent oak (Quercus pubescens Willd.), Italian oak (Quercus frainetto Ten.) and the Holm oak (Quercus ilex L.). Samples were collected in Dalmatia, Croatia. Foliage and wood biomass was independently measured as weight and volume. Independent estimators were crown diameter, height and number of stems. General linear modelling was used for model development. The yielded models are appropriate for the quick and confident estimation of the population biomass (foliage and /or wood) of the examined oak species in second growth forests.
